基于多功能机器与多能工的动态单元制造系统模型

摘要

为了成功地实施动态单元制造系统，同时考虑技术性问题（包括生产单元构建和设计、生产单元之间与生产单元内部的物料移动等）和人员问题（包括员工工资、员工雇佣和解雇等），综合研究和分析了多功能机器和多操作技能员工的动态单元制造系统的生产单元构建、生产单元之间与生产单元内部物料移动、库存和延迟生产、员工分配和柔性生产路径，创新性地提出一个整合的混合整数规划模型。通过遗传算法对数值试验求解，结果验证了新模型的可行性和有效性。%In a production environment of high variety and low volume, product mix and demand usually change under a multi-period planning horizon.The dynamic cellular manufacturing system ( DCMS ) is a well known strategy that typically improves manufacturing efficiency in sucha production environment.To implement DCMS successfully both technical issues ( cell formation and design, intercellular and intracel-lular material movements etc) and human issues ( salary, hiring and firing) need to be considered.An in-tegrated mixed-integer model is developed to comprehensively investigate and analyze cell formation, inter-cellular and intracellular materials handling, inventory and backorder holding, operators assignment and flexible production routing considering multi-production planning with multi-functional machines and multi-skilled operators where each period has different demands.The optimum of the numerical example is solved using a genetic algorithm and it proves the proposed model to be feasible and effective.
